Built FAR and MAXIMUM ALLOWABLE FAR
Built FAR The Built Floor Area Ratio (FAR) is the total building floor area divided by the area of the tax lot.This calculation by City Planning is based on rough building and lot measurements provided by the Department Of Finance. FAR is calculated using the TOTAL BUILDING FLOOR AREA and the LOT AREA. The LOT AREA contains street beds when the lot contains ‘paper street’ i.e., street mapped but not built.
MAXIMUM ALLOWABLE FAR Either the Maximum Allowable Residential Floor Area Ratio (FAR) or the Maximum Allowable Commercial FAR.

If ZONING, ALL COMPONENTS 1 begins with M (manufacturing) or C (commercial) and Maximum Allowable Commercial FAR is greater than or equal to the Maximum Allowable Residential FAR then the Maximum Allowable Commercial FAR is displayed.

If ZONING, ALL COMPONENTS 1 begins with M (manufacturing) or C (commercial) and Maximum Allowable Residential FAR is greater than the Maximum Allowable Commercial FAR then the Maximum Allowable Residential FAR is displayed.

If ZONING, ALL COMPONENTS 1 begins with R (residential) then the Maximum Allowable Residential FAR is displayed. The Maximum Allowable Floor Area Ratios are exclusive of bonuses for plazas, plaza-connected open areas, arcades or other amenities.

Number of Floors
Number of Floors In the primary building on the tax lot, the number of full and partial stories starting from the ground floor.

NOTES: If the NUMBER OF FLOORS is zero and the NUMBER OF BUILDINGS is greater than zero, then NUMBER OF FLOORS is not available for the tax lot. If the NUMBER OF FLOORS is zero and the NUMBER OF BUILDINGS is zero, then NUMBER OF FLOORS is not applicable for the tax lot.

Tax Class Category
CodeDecode (Lindy Davies)
1 indicates the following types of primarily residential property:
- One-, two-, and three-family homes
- Condominiums of three stories or less that were originally built as condominiums
- Condominiums of three dwelling units or less that were previously a one-, two-, or three-family home
- single-family homes on cooperatively owned land, also known as "bungalows"
- certain vacant land zoned for residential use or, if not located in Manhattan south of 110th Street, vacant land adjoining improved Class 1 property.
2 Tax Class 2 is for all other primarily residential properties, including any residential condominiums not in Class 1. This includes co-ops, but does not include hotels, motels, or other similar property.
3 Tax Class 3 includes real estate of utility corporations and special franchise properties, excluding land and certain buildings. (We should note that class 3, which includes utilities' capital but no land at all, has little to do with our current analysis.)
4 Tax Class 4 includes all other properties, such as stores, warehouses, hotels, and any vacant land not classified as Class 1.
